Class JSONSerializer

java.lang.Object
  org.xml.sax.helpers.DefaultHandler
      org.weborganic.aeson.JSONSerializer

All Implemented Interfaces:

ContentHandler, DTDHandler, EntityResolver, ErrorHandler

public final class JSONSerializer
extends DefaultHandler
implements ContentHandler

This serializer is a content handler implementation so that it can be used directly against an XML instance or wrapped inside a SAXResult implementation.

When used as part of a SAXResult, it is preferable to use the dedicated JSONResult class.
